Dynojet's read flywheel horsepower, not wheel horsepower. Right there in black and white straight from the inventor of the Dynojet Dynamometer.
I was just about to bring that up. Maybe it would have held more water since I don't have BR in my sig

Let's face it. This whole conversation is a waste. No one is going to read any of these posts (no matter how right they are) and have an epiphany that they were wrong.

Whoever said 160mph trap on 700 whp is ridiculous needs to take into consideration the true drivetrain loss realized through an All Wheel Drivetrain. It is around 30%. So on a TRUE 700 awhp you are putting 1000 at the crank.... Still sound ridiculous?????

both dynojets ive ever used in my lifetime sure as hell didn't read flywheel hp. plus posting a bike article on a car forum for info?

You have not worked for MD in YEARS. Long before we ever purchased the unit.

Evom members will notice a striking trend in the complaints. Each one of them share a strikingly similar signature noting support or sponsorship from the same company.
Actually I've read the entire thread, but thanks for implying I haven't. Yes, I didn't feel like going back to find 3365lbs and typed a round number of 3400lbs. My fault.

So let me rephrase. I'm still trying to figure out how TTP's Evo weighs 3365lbs.

It has nothing to do with BR being in my signature. I just can't figure out how you could have added weight to a car?? My car is a full street car - everything you mentioned on your car and not one single lightweight part, even has a sunroof - and it weighs 2990lbs with 3/8's of a tank of gas.

As for not working for MD, correct, I quit in October 2007. But I still talk to people there and know they haven't changed their formula for calculating horsepower - it's patented...they aren't going to change it. Therefore its still the same as when I worked there.

I sold dynos there for 4 years. Dynos were my job and knowing if they were working correctly was part of my job. I didn't magically forget how to know if they were working correctly or not once I left there.

As for those online horsepower calculators - most of them spit out Dynojet/flywheel horsepower numbers, not Mustang Dyno horsepower numbers.

i didn't read through the article thoroughly but the first entire page is bike related. as far as dynojets reading flywheel hp, how comes you can take a car thats rated at the factory at x amount of hp (flywheel) and put it on a dynojet and make lower numbers? how can a dynojet be a true flywheel hp rating when you're on rollers? i don't get it.....

im not reading the article. common sense tells me any dyno that youre spinning rollers on to determine your speed with your tires is NOT flywheel rated. they make dynos that rate flywheel and they are with the engine out of the car.

Common sense should tell you that a dyno uses a computer that uses a mathematical equation that can make ANY number in accordance to the given equation.

OK then don't read the article. Here's a excerpt from the article that I'm quoting again.

Originally Posted by Hot Rod Article
Dynojet's final number-fudge was arbitrarily based on a number from the most powerful road-going motorcycle of the time, the '85 1,200cc Yamaha VMax. The VMax had 145 advertised factory horsepower, which was far above the raw 90hp number spit out by the formula. Meanwhile, existing aftermarket torque-cell engine dynamometers delivered numbers that clustered around 120. Always a pragmatist, Dobeck finally ordered his Chief Engineer to doctor the math so that the Dynojet 100 measured 120 hp for a stock VMax. And that was that: For once and forever, the power of everything else in the world would be relative to the '85 Yamaha VMax and a fudged imaginary number.
Cliff notes for that article.
- Dynojet numbers are based on a fudge factor that the inventor of the Dynojet based on what he felt a 1985 motorcycle's horsepower should be. This number just happened to coincide with the horsepower this motorcycle made on an engine dyno.

I'm putting FACTS right in front of you, yet you continue to ignore them and go with your "common sense"

It's not that dynojets give true Flywheel HP ratings. The equation is BASED on flywheel hp. The point is that they DON'T give true WHEEL HP figures.

heres a better article. http://web.archive.org/web/200707181...+inertia_1.htm

does any dyno give true wheel horsepower tho? i would say no, because they all have **** where the operator can mangle the true readings. therefore all dyno numbers are emulated no?

You don't know what figures are being used in those calculators. None of us do. That's why that cannot be relied up to solve this argument. The theory of mathematics is that math can be repeated with the exact same outcome 100% of the time. In this case, these calculators do not do that because they are using different formulas to account for drivetrain losses. Also, we don't know if they are accounting for RWD whp, AWD whp, FWD whp, etc, etc.

One fact remains...online calculators are NOT a reliable source to determine how fast a car will actually trap in the 1/4 mile. This is bench racing at it's finest.

The only number that matters is that TTP's car is capable of a 143mph trap for his claimed whp. There are many other cars with lower whp numbers from other dynos that are trapping significantly faster. These are all facts from real world track experience (not online calculators).



I gave you the formulas to calculate it's printed in black and white. I didn't look at the calc you posted.

Looked at the one for whp. Took the formula, took TTP's #'s, did the math, and what do you know math works. It's FRIGGIN PHYSICS. It tells me and the world in PLAIN FRIGGING ENGLISH that TTP's dyno is a close indication of the WHP the car is making looking

And that DB, GST, CBRD, and My Moms Mustang dyno read a lower WHP # that is likely Mustangs standard. PERIOD.

I'm done bro your really just don't get it. It's math it's repeatable over and over again.

You still have not read it correctly because you do not want to. For the same reason you have ROUNDED UP TO A HEAVIER WEIGHT, is the same reason you have purposely neglected the fact that the driver is 200lbs to try and make it look like we are stating a heavier weight.

The car is 3165lbs without driver.

From your article
In reality DJ has already added in 15 or 20% to their 200 DJHP number
